*The present invention relates to a snow reinovalfappa'ratus which is icapable of han' dhng practically any'lrindfofheavy wet siiow ,o`r finedry s1iow,"but whichis' pecu# liaralyv siiited'for breaking up and removing hard 'crusted ysnow or lsnow-'which hasbeen stored piles and whichV become firmly packed while awaiting remova'll" f di/lpre specifipally the devicev is in the natureV of an attachment forftrnclrs, tractors, or thelillr'e, and' includesa'pair of'ribbed, oppositely revolving cylinders Vwhich break. upthef'har'd ypacked snow and carry itto "a fan Echaniber, "fromv which the snow is impelled either" into al suitable 'receptacle such as a truck, or carried off to the side "of the roadl' ""1 A An object of the invention is to provide a device of this character which' vwill bezemeient in action, and whichinay be con-'Jeniently controlled bythe drive'rofa 'truckfor other vehicle'upon whichthe apparatus is carriedl i Further objects of *the invention are` to provide snow removal apparatus of'simple, practi l construction, whichfwill berugged ble inz use',` and which 'mayibe in'zinufacturedi applied "and f 'operated with comparative economy. r

Lith theaborer noted and other objects in viewfthe invention `Aconsists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claim. The invention may be more fully understood from the following de-k scription in connection with the accompanying drawings, wherein- Fig. 1 is a view partly in section, but mainly in side elevation illustrating the forward end of a truck or other motor vehicle and showing the device of the present invention mounted thereon.

Fig. 2 is a top plan view of Fig. 1.

Fig. 3 is a front elevation thereof.

In the drawings 1 have used the reference character 10 to designate the main chassis frame of a vehicle including traction wheels 11. This vehicle may be driven from an enginev (not shown) located under a hood 12, or may if desired be operated from one of the additional motors which will be later described.

Mounted forwardly of the vehicle are a pair of drums or cylinders 13 disposed with their axes in a vertical plane and rotating in opposite directions. vThe ydrums are spaced slightly apart forthe passage ofsnow vwhich i'spiclred rip the ribs or cleats 14 onl the exterior of the drums. It willgbenot'ed that,y

the cleats 14 'are' arranged in a spiralfseries, and their VFdirectionl ofcurv'ature is reversed at approximately the .center of thev drum. Thusithe cleats run spirallyin one'dire'ction about eacli drum throughtheflower portion.

thereofg and: spirally inia reverse .direction about 'thed'rum' atithe upperihalf thereof. This: arrangement of cleats provides Qin effect, a series offVeshaped lea'tswith their apices at' approximately' ithe 'center ofthe drums, and'. their legsV terminating' ati the upper and lower edges fofithe drum. Thus in Vnormal perationwhen the two drums are moved into a snow bank orsnow. pile, the tendency of the. cleat arrangement willube to carry the snow,betweenthe.:drums` and force 'it toward .thefcenter o ffthe druins, as will. be readily understood.v i

wThe manner of mounting and driving .the .drums .is subjectfto a widepvarietyof, variations5l'andV as a, matter offact, theidrum mou'ntin'g. has been. shown` ratherl diagrammatically; Apair. of. uprightirameibars ,15 secured to :the: vforward',end Vof the chassis 1*'0 are "secur.e d..to.l the" upper ends of diagonal `bracing members 16;.@the lowerfend's of .which are riveted; hinged or otherwise sef cured to the chassis at 17. Cross arms 18 mounted on the vertical frame bars 15 below the upper ends of the latter, have their ends bolted respectively to the frame bars 16 and to inclined frame bars 19 disposed forwardly of standards 15, and carrying at their forward ends a transverse bearing plate 20. The upper ends of frame bars 19 are secured to the upper ends of the standards 15.

The two drums 13 are formed with upper hubs or spindles 21 having bearings in the plate 20, and with lower hubs or spindles 22 having bearings in arms 23 projecting forwardly from the lower ends of the standards 15.

Mounted upon a platform or frame 24 which is supported by the braces 16 and by standards 25, is a prime mover such as a gasolene engine 26. Projecting forwardly from the engine 26 is a hollow arm 27 which provides a bearing for a power shaft 28. The hollow arm 27 is preferably rigid with a transverse housing 29 extending above the two drums7 and mounting a power transmitting shaft 3() which has a worm and gear connection at 3l with the shaft 28.

The ends of the shaft 30 carry bevelled pinions 32, meshing with bevelled pinions 313 keyed to the axles 2l ot the drums to eii'ect simultaneous rotation o'tl the drums in opposite directions as indicated by the arrows in Fig. Q.

Disposed immediately behind the drums and mounted in any appropriate manner on the forward end ot the chassis l0 is a 'tan casing 34 housing a tan 35 driven from a suitable motor 36 supported on the chassis. Curved blades 3T carried by the fan casing and projecting forwardly into the space between the drums, guide the snow which is delivered by the drums into the tan easing, trom whence the tan throws it outwardly through a discharge pipe 3S either to the side ot the road. or into a wagon or truck which may be provided Yfor its reception. lt will be noted that the forward ends ot the blades 3T terminate closely adjacent the outer surt'aces of the revolving drums 13. so that the blades 3T serve as cutters to remove excess snow Ytrom the surface of the drums and cause the snow to be drawn into the 'tan casing by the fan 35.

Carried by the arms Q3 is a scraper plate or plough 4U which serves as an inclined delivery platform up which the snow is carried as the snow removing apparatus is moved into a snow bank or snow pile.

ln many instances it may be desirable to tooth alternate cleat-s to attain a more positive biting action and breaking action when removing a pile of hardened snow. From the foregoing description it is believed that the operation of the device will be evident.

The truck is moved torwardly carrying the cylinders into a snow bank or snow pile. The snow broken up by the cleats on the drums and ted into the tan chamber from whence it is discharged through the lateral discharge pipe 238.

Obviously the particular manner of supporting the drmns on the 'forward end of the truck, and the manner ot rotating the drums is subject to a wide variety ot variations. Obviously also the drums and the tan might bc driven from the usual truck motor in any convenient manner, thereby avoiding the use ot the additional motors QG and Various changes and alterations might be l"- made in the general form and arrangement ot parts described without departing Atrom the invention. Hence I do not wish to limit myself t0 the details set forth, but shall consider myself at liberty to make such changes and alterations as fairly 'tall within the spirit and lscope ot the appended claim l claim:

A snow removing apparatus adapted to be mounted on the vforward end ot' an automotive vehicle, including a pair ol: oppositely revolving cylinders externally spirally ribbed to deliver snow between them. a tan behind the cylinders and a laterally disposed discharge pipe through which thc snow delivered to the tan is blown. and means for guiding the snow from the c vlinders to the tan, including a pair guide and scraper plates, the Yforward ends of which terminate closely adjacent the walls of the cylinders.
